Mage Vs Champs

Alright Guys i recently just got back into the game and it took some thinking i have a champ and a mage champ is 213 mage is 215 i focused on mage when i came back pvp/pvm build so now im not exactly sure whats better for pvm/pvp even though mages have more distance with permafrost for some reason champs still sometimes get there stun in before i do they have 16m i have 18 right now i have full chiv JO ring arua neck d7 and earring d7 if thats helps.
mages + high aoe span
+ higher ap
+ heals (pvm)
+ sleeps,stuns
- low defense
Champs+ Aoe's
+ high ap
+ high def
+ alot of stuns
+ high hp
+ good accuracy
now this is all i see between them if u guys can help out im not sure which to choose because there both good pvm n pvp and if someone could tell me if champs can solo farm (ruins) without hp pots or anything please it would help thanks

oh yea n the debuff i rememberd right after i posted well i was going to add on to berrys note about 100% mute mages also have 100% mute and another thing + mages it also has hellfire? the burn . and does anyone kno why 16m hits sometimes before 18?

If you mean why dies a champs weapon launcher beat a mages permafrost chill even though it has less range; all moves have a certain proriety some moves beat out other moves, same reason why a raiders sucker punch hits before soul wreck even though it has 2m range vs soul wreck's 7m.
